To aZZ whom it may concern:

Be it known that-l, EDWIN G. (dreams,

a citizen of the United States, and a resident of Los Angeles, in the county of Les tingeles and State of California, have invented certain new and useful Improve-- below the geometric central axis of the main planes. I attain these objects by means of the device shown in the accompanying drawings, in which Figure 1 is a front elevation of a glider.

Figure 2 is a side elevation of the device.

Figure. 3 is a view similar to that illustrated in Fig. 1, except that it is tipped at an angle laterally, and provided with can tain reference charactersfor further explanation in a following description.

Figure t is a fragmentary detail perspective view of the lateral extremities of the wings or planes.

Figure 5 is a top plan View of the device.

The Fig. l. is a clear illustration of the principal parts of-the device, as the fuselage 17, landing gear 18, a rudder 14, a horizontal stabilizer 16, with or without elevators attached a pair of wings 7, held in position by ;...r.'tical struts 19,"and carrying crossed auxiliary planes 4, or the intersection of the continuation of planes 7.

Referring to Fig. 3, the machine is shown tipped at an an le laterally. Gravity acts upon the planes thru the center of grav- 45 ity 3, while the sustainingforce of the air 1, upon the cross planes i, which are in a nearly horizontal position, one at each end, exerts an equal pressure upon each lateral extremity, regardless of the angle at which the plane is tipped, thus causing the planes 7 to balance on the center of gravity 3 as a fulcrum, and so rotating the planes 7 into a horizontal position. The center of gravity 3 should lay below the geometric center 15 of the wings I for this to take place.

Simultaneously with this the other pair of cross planes 4, which are in a nearly per-1 pendicular position, one at-each end, are acted upon bythe air in a horizontal direction 2, thus preventing sideslipping. The construction of said cross planes 4- is amplified in the Figs. 1 and 4L.

1 am aware that changes may be made in the general arrangements and combinations of the various parts, as well as in the details of construction of the said parts, without departing from the scope of the present invention as set forth in the foregoing specifications, and as defined in the clauses of the claims which are appended to the said specifications. Hence, I do not limit my invention to the exact arrange .ments and combinations of the various parts as described in the said specifications, nor do I confine myself to the said parts as illustrated in the accompanying drawings.

1.- An airplane comprising horizontal wings terminating in an upward and downward direction so as to cross, a fuselage, a rudder, and stabilizers adjacent said rudder.

2. An airplane construction comprising a fuselage, horizontal wings mounted adjacent said fuselage, one above the other, and other wings secured to the ends 'of said horizontal wings projecting upward and downward so as to cross.

3. An airplane comprising a fuselage, stabilizers positioned at the end of said fuselage, a rudder secured adjoining said stabilizers, horizontal wings mounted. adjacent said fuselage. and cross wings forming extensions of said horizontal wings in an upward and downward direction so as to 4. An airplane comprising a fuselage, stabilizers positioned on said fuselage, a rudder mounted between sa1d stabillzers, a

horizontal wing secured to said fuselage,

and auxiliary planes intersecting each other at, or nearly at right angles so as to cross,

cross.
